Abstract

PROCEDIMIENTO PARA LA COMPENSACION TERMICA DE UN CIRCUITO MAGNETICO, CUYAS PERDIDAS AUMENTAN EN FUNCION DE LA TEMPERATURA. CONSISTE EN INCORPORAR EN LA PROXIMIDAD INMEDIATA DEL CIRCUITO, DE LA INDUCTANCIA (3, 4) O DE UNA EXTREMIDAD DEL NUCLEO MAGNETICO (6), UNA PASTILLA (1) DE UN MATERIAL CUYA PERMEABILIDAD MAGNETICA ES FUNCION DECRECIENTE DE LA TEMPERATURA Y EL PUNTO DE CURIE ES SENSIBLEMENTE IGUAL AL VALOR MAXIMO EVENTUAL DE LA TEMPERATURA AMBIENTE. EL MATERIAL DE LA PASTILLA (1) SE ELIGE PREFERENTEMENTE DEL GRUPO QUE COMPRENDE EL HIERRO SULCE Y EL FERRONIQUEL. DE APLICACION EN UN DISPOSITIVO DETECTOR DE MASAS METALICAS QUE INCLUYE MEDIOS DE SEGURIDAD.
